Hello everybody.I have a tech friend who doesn't have access here and he asked my help.He has an mpc 2550ricoh machine and after one copy it shows sc 400.I followed the service manual and told him to clean the id sensor which is on the side of the machine under the belt on a small board.3 sensors which have been cleaned but it keeps showing sc 400.Any help?

Re: Mpc 2550 error sc 400
Clean the I.D sensors and take off the transfer unit metal bracket with the three holes as the inside of that will probably be covered in toner as well.
Also clean the positioning sensors for the paper transfer roller cam, that can play havoc with the MUSIC adjustment pattern on the transfer belt.- Knowledge not shared, is eventually knowledge that becomes lost... like tears in the rain.

Re: Mpc 2550 error sc 400
You can clean these sensors without taking the ITB unit out, but it is easier to do it. You can also clean underneath the ITB unit but if you don't remove the plate (see above) the dust will vibrate back down onto the sensors.
If you clean it, reboot the machine and it returns, replace the whole ID board (save the black spacers from the previous board!).Comment

Re: Mpc 2550 error sc 400
Sc 400 is also caused on these models by a blocked exhaust fan filter (check the one one the back cover right behind the fusing section). Also there is a motor assembly on the front right (behind the L - shaped light brown inner cover.) If this is not lubricated it also causes the same Sc and changing the I'd sensor board would not fix that.Press the GREEN button!!Comment
